Boat wake system

Abstract

A water craft having a bow and a stern including an engine of sufficient thrust to create an enlarged wake at the stern of the boat as the boat moves along the surface of a body of water. The water tight compartment is positioned to carry water below the water line and essentially astride the centerline or keel of the boat. The compartment is adapted to contain liquid water in an amount sufficient to enhance or equalize the size of the boat wake. The compartment extends from a point forward of the transom and engine, and extends to a point forward of the midpoint between the bow and the stern, and terminates short of the bow while serving to exert downward force on the bow against the water when the water craft is underway and the compartment carries water.

1. A water craft comprising:
 a hull having a bow and a stern 
 an engine of sufficient thrust to create an enlarged wake at the stern of the boat as the boat moves along the surface of a body of water, 
 a water tight compartment essentially filled with ballast water and positioned to carry essentially all of the ballast water below the running water line of the boat, said water tight compartment being essentially astride the centerline or keel of the boat, said water tight compartment containing ballast water in an amount sufficient to lower the entire boat in the water at steady planing speed and enhance or equalize the size of the boat wake, 
 and said water tight compartment extending from a point forward of the transom of the boat and engine, extending to a point forward of the midpoint between the bow and the stern, and terminating short of the bow, said ballast water in said essentially filled water tight compartment serving the exert downward force on the bow against the water when the water craft is underway at steady planing speed to create a larger wake and an enhanced amount of lift water for an enthusiast being towed behind the water craft on a towable water sports device. 
 
   
   
     2. The water craft of  claim 1  wherein the water craft is a 16′ to 32′ boat used primarily for towable water sports. 
   
   
     3. The water craft of  claim 1  wherein said watertight compartment comprises an interior portion of the water craft construction. 
   
   
     4. The water craft of  claim 1  wherein the watertight compartment comprises a bladder. 
   
   
     5. The water craft of  claim 1  including an air vent system for said compartment located at the physically highest and most forward part of said compartment. 
   
   
     6. The water craft of  claim 5  wherein said system further includes a length of rubber or suitable flexible hose connected to a vent through the boat hull above the water line.
